看起来我和OP的人有着同样的问题：但我没能把它修好

执行基本rails应用程序，如中所述：尝试

rails g bootstrap:install

失败

我的系统上r/r的基本版本为： ruby v 1.9.2p320， rails 3.1.0 关于雪豹10.6.4

我可以在本地系统上复制的方式：

rails new bsapp --skip-stylesheets
cd bsapp
rails g scaffold product name:string price:decimal --skip-stylesheets

将gem'twitter bootstrap rails'添加到gemfile中的资产组

bundle update
rails g bootstrap:install

这就是问题所在

问题的根源是v8/therubyracer/libv8的安装不好/旧/不存在

libv8 gem的某些版本直接安装失败，而那些安装失败的版本——它们花了几个小时，所以我认为它们挂起/崩溃了（我正在使用上网本，所以这是可以预料的）

目前，以下配置适用于我：

gem "libv8", "3.11.8.13"
gem "therubyracer", :require => 'v8'
gem "less-rails"
gem "twitter-bootstrap-rails"

在开发和生产中（heroku）

rubyracer或libv8上都存在与此相关的github问题，其中提到了x86/32位处理器的问题——我现在记不起来了。
